About one year before the Potomac crash, I left Helsinki on the same aircraft type...very hairy 25 minutes and the aircraft was described by a ground engineer as being in 'a doomed posture' and a '120 degree flip roll'.
It had been de iced but take off was delayed and ice reformed...I tried to send the Skipper a bottle of special Scotch, but BA declined.
I wish there had been someone observant enough to give a warning to the flight crew that night.
